"The way to describe is that he didn't feel 100 percent after getting hit. He felt OK right afterwards and then he started feeling a little fuzzy," general manager Ruben Amaro said.

"The protocol is to wait a day or so to do an impact test, so he's going to be out a couple of days at least."

Amaro said the first determination was whether Utley should fly to Milwaukee with the team after the game. The Phillies begin a four-game series Thursday night.

"We think it's very, very mild, but we're going to be cautious with it obviously," he said. "You don't want to mess with the head … we're not going to mess with the heart and we're not going to mess with the head.

"When you get a 90-plus mile an hour fastball off your melon, you have to be cautious about it regardless of what kind of gear you're wearing. He's basically going to do nothing tomorrow."

Amaro said the Phillies also plan to activate shortstop Jimmy Rollins, although he will only be used in an emergency. The expanded rosters provide a bit of a luxury.

"I think he's going to be ready to go," Amaro said. "Physically, he's ready to go. But again, we're trying to be cautious with Jimmy. (But) we're going to activate Jimmy and have Charlie use him in emergency purposes in case he needs him. Hopefully, everyone can stay healthy and Chase will be back with us."
